D- DAMPER
The barometric control must be adjusted so that the maximum draft measured at the furnace outlet is limited to -
0.06 in. w.c. Please note that a draft higher than -0.06 in. H
hand, the minimum draft to be respected is -0.04 in. w.c. in the evacuation pipe.
E- COMBUSTION AIR
When the furnace and the chimney are completely cold, it might be necessary to provide fresh air by opening a door
or a window for a few minutes while lighting the fire.
Take note that a house constructed or renovated in order to be airtight is liable to lack fresh air necessary for the
proper combustion of a flame producing heating appliance.
In such a case, when starting up the fire, do not operate appliances that evacuate air outside the house such as:
-
Range hood
-
Air exchanger
-
Clothes dryer
-
Bathroom fan
-
Ventilated central vacuum system
NOTE:
It is recommended to install an outside air inlet of minimum 4" diameter in the room where the heating appliance is
installed (see drawing below). It is preferable to choose a wall that is not exposed to dominant winds, depending on
the conditions surrounding your house.
N.B.
The owner of the furnace is responsible for the room salubrity in case of negative pressure or
temporary negative pressure.
